Thank you all so much for your incredibly thoughtful responses! I had never thought as Loren for a nickname for Florence. I also had never really noticed how alike Camilla and Miles are. Perhaps that's why I like it.
Our dream family has three children and I love Isaac and Miles together, so I don't want anything to spoil that.

I really wanted names like Poppy, Ruby, Violet etc. before I became pregnant but early on in the pregnancy my heart kept telling me this baby won't wear those names.

Josephine and Annabel are my DH's picks and they are growing on me. I love the history of Josephine and meaning of Annabel.
I guess I'll work on some middles and talk it over with DH when he's receptive to the discussion again
